Daily 0.5 km, 1 km and 5 km resolution Greenland, Arctic Canada and Iceland glaciated area
albedo grids are available beginning April 2000 and (currently ending) October, 2017. The data
are based on NASA MOD10A1 Collection 6 data with de-noising, gap filling and bias correction
after Box et al. (2017). When the solar illumination is inadequate for an accurate
MODIS retrieval in winter months (January, February, November, December), April values are
swapped in. All days of the year and all non-ocean pixels have an albedo value.

The grids are available here at 5 km resolution for Greenland and north-eastern-most Arctic
Canada. However, data covering the entire Canadian Arctic and Iceland area also available. Data
at the native 500 m resolution and 1 km resolution are available on request from jeb@geus.dk

The data are distributed in NetCDF format and contain latitude, longitude, land mask. The
map projection is Polar Sterographic.
